7、dentifiedand separated into component parts.Those component partsare measured and reported as a percentage of the whole.5.Significance and Use5.1 This test method may be used for acceptance testing ofcommercial shipments of bulk plumage.Acceptance tolerancesof content must be established between the
8、 purchaser and sellerof bulk shipments of plumage,which also must comply withstate and federal agency regulations,as appropriate.5.1.1 In case of a dispute arising from differences inreported test results when using Test Method D4524 foracceptance testing of commercial shipments,the purchaser andthe
9、 supplier should conduct comparative tests to determine ifthere is a statistical bias between their laboratories.Competentstatistical assistance is recommended for the investigation ofbias.As a minimum,the two parties should take a group of testspecimens that are as homogeneous as possible and that
10、arefrom a lot of material of the type in question.The testspecimens should then be randomly assigned in equal numbersto each laboratory for testing.The average results from the twolaboratories should be compared using Students t-test forunpaired data and an acceptable probability level chosen by the
11、two parties before the testing is begun.If a bias is found,eitherits cause must be found and corrected or the purchaser and thesupplier must agree to interpret test results in the light of theknown bias.5.2 This test method may also be applicable to the accep-tance of consumer products that use plum
12、age as a fillingmaterial.Such consumer products include pillows,comforters,sleeping bags,garments,furniture,and mattresses.Acceptancetolerances of content are established by distributors,importers,state or federal regulatory agencies.See 5.1.1.1This test method is under the jurisdiction ofASTM Commi
